At Jack Henry, we’re more than a technology company, we’re a force for good in financial services. We’re redefining how community banks and credit unions connect with the people they serve. Our mission is rooted in people inspired innovation, empowering financial institutions to deliver seamless, secure, and human centered experiences. We deliver cutting-edge solutions that are paving the way for the next generation of digital banking and payments, but our true impact begins with our associates. If you’re ready to help transform an industry and grow with a company that values purpose, collaboration, and excellence then we’d love to meet you.

Join Jack Henry’s Developer Experience team and help shape how our engineers build, deploy, and scale modern financial technology. In this highly impactful engineering role, you’ll define frameworks, create tooling, and provide automations that allow developers to ship secure, reliable code faster. You’ll combine full-stack and infrastructure expertise to build and centralize performant, scalable platform tooling in our internal developer platform. Finally, you’ll foster relationships and partner with our engineering and support teams to better understand how we can remove friction and improve their existing processes. This is an opportunity to establish best practices, influence our technical direction, and create solutions that serve as both a North Star and a foundation for engineering teams across Jack Henry. This role may require up to 5% travel for meetings, training, or conferences.

This position may be worked remotely within the United States, with the exception of California. All positions, regardless of location, may require an onsite interview or in-person onboarding requirement to verify your identity.

• Write code to build full stack platforms under minimal supervision.
• Plan, design and build the core tooling platforms used by all of Jack Henry’s engineering teams.
• Debug critical production issues that may impact multiple sites and services.
• Focus on site state and health with the discipline that allows us to easily and automatically move workloads to avoid failure.
• Work with engineering teams to understand their priorities and emerging needs to prioritize solutions that keep pace with product development.

• Advocating for coding standards and best practices.

• May perform other job duties as assigned.

What you’ll need to have:

• A minimum of 4 years in software engineering, systems engineering, DevOps, and/or infrastructure as code environments.

• Experience in Golang, Rust, or NodeJS and React or another front end framework.
• Experience with a major cloud platform, with Google Cloud Platform preferred; AWS or Azure experience is also acceptable.
• Familiarity with the full life cycle of software development, from design and implementation to testing and deployment.

What would be nice for you to have:

• Bachelor’s degree.
• Experience with databases like MongoDB or PostgreSQL.
• Understanding and practical experience in declarative service infrastructure environments (e.g., Kubernetes, Terraform, Docker).
• Experience working with Internal Developer Portals such as Backstage or other DevEx tooling.
• Experience in UI/UX development, including the ability to write HTML and CSS.
• Experience in implementing security best practices within all phases of the software development lifecycle
• Experience writing and documenting standards and practices.

If you got this far, we hope you’re feeling excited about this opportunity. Even if you don’t feel you meet every single requirement on this posting, we still encourage you to apply. We’re looking for passionate, driven individuals who align with our mission and can bring unique perspectives to our team.
